Researchers have built an artificial retina out of perovskite materials that can detect light in a similar fashion to the human eye. In tests, the device was even able to recognize handwritten numbers with a high degree of accuracy. https://newatlas.com/electronics/perovskite-artificial-retina-read-numbers

What a gorgeous miracle. I know quite a few people who've had retina issues. To think this could restore sight to them! Thank you for sharing.
